OCT Biometry (B-OCT): A New Method for Measuring Ocular Axial Dimensions

Table 2

Interobserver reproducibility results for B-OCT using REVO NX based on the first readings from each session taken by 2 clinicians in a sample of 50 eyes.

Parameter	1st observer, mean ± SD	2nd observer, mean ± SD	Sw	TRT	CoV (%)	ICC
AXL (mm)	23.93 ± 0.80	23.93 ± 0.80	0.02	0.04	0.06	1.000
CCT (μm)	555.72 ± 26.55	555.54 ± 27.25	2.21	6.12	0.40	0.993
ACD (mm)	3.58 ± 0.28	3.59 ± 0.28	0.06	0.06	0.65	0.993
LT (mm)	4.02 ± 0.22	4.02 ± 0.22	0.03	0.07	0.63	0.985

AXL: axial length; CCT: central corneal thickness; ACD: anterior chamber depth; LT: lens thickness; Sw: within-subject SD; TRT, test-retest repeatability (2.77 Sw); CoV: within-subject coefficient of variation; ICC: intraclass correlation coefficient.
